I've had this phone for about a month now. No problems whatsoever, until the other day. My phone was turned off. Then, it "magically" turn on ans started ringing. I turned my phone back off for a while. Later, I turned it back on and the second the home screen pops up, like 10 force close screens pop up. I can't text, internet, nothing. No settings either. I click the phone tab at the bottom and another force screen pops up, same as everything else. It also shows I have no signal at all, when normally I have almost full bars. A few days prior to this, my phone would phase in and out of service for no reason. Any suggestions?
